Why did apple choose Obj-C over something people know and understand like
C++? or even C.
1) Because Openstep and its predecessor was written in Objective-C almost 15
years ago. Cocoa is Openstep 5.0. Do you remember what C++ was like 15
years ago. The "virtual" key word had just been introduced.
2) Read the section on "Why Objective-C" in

How many languages do you know ? I say the more the better.
You love Interface Builder but not Objective-C ? Why do you suppose tools
like Interface Builder are not available for other platforms/languages ? It
is Objective-C that makes it possible. To make it with C++, you would have
to write an Objective-C like runtime in C++. Isn't it interesting that IB
is almost 14 years old, and it has not changed much in that time ?

Are you that hung up on syntax or were you unable to grasp the dynamic

1) Because Objective-C mixes Smalltalk and C
2) Because Brad Cox liked []
3) Because () is already overused and can be confused for a function call.
Messages are very different from function calls.

In this case, Objective-C and C++ are about the same age. Some would argue
that Objective-C came first and C++ is the new guy considering that in the
early days C++ was "C with classes" and did not support polymorphism
(considered essential for an OO language). Furthermore Objective-C works
like Smalltalk (the original OO language for which the term "Object
Oriented" was coined.

And Cocoa makes the Java standard libraries look like buggy slow toys in
comparison and for some application domains. The main reason to use
Objective-C is to be able to use Cocoa and to be able to use the language
features that make Cocoa possible.

If you ever understand Cocoa, I assure you that it will change your life.
Even you future C++ code will look and work differently.
I recommend that you learn Lisp, Smalltalk, Eiffel, Perl, and at least one
assembly language. Broaden your horizons. Then come back and look at C
derived languages with a different admiration and sense of limitations.
